| Abstract | ||||
| A 2×4 factorial arrangement was performed includingtwo levels of garlic powder (0 and 0.5%) and four used levels of lead acetate (LA0, 300, 600 and 900 mg/kg diet)andeffect. One hundred twenty unsexed 1-week-old seventy two (120) Ross broiler chicks were randomly distributed to 8 dietary treatment groups (15 birds each). in broiler chickens in lead exposed broiler chicksas antibioticEach treatment Divided into 8treatments (T0-T7)each treatment was subdivided to 3 replicates and each replicate contained 5 chicks. Growth performance and carcass traits were studied. Where T0 served as Control,T2 as provided with garlic 5 g/ kg diet, T2 as provided with Lead 300 mg/ kg diet, T3 had lead 600 mg/ kg diet, T4 had Lead 900 mg/ kg diet, T5 as provided with Lead 300 mg/ kg diet+5 g garlic powder/ kg diet, T6 had lead 600 mg/ kg diet+5 g garlic powder/ kg diet, T7 had Lead 900 mg/ kg diet+5 g garlic powder/ kg diet for 42 days. The oObtained results showed that can be summarized as follow:showed a significant (p<0.01) improvement in feed conversion ratio of birds kept on a diet containing (0.5%) garlic and the final live body weight, daily body weight gain and survival rate were significantly (p<0.01) increased, whiledaily feed intake significantly (p<0.01) decreased.Butdietary lead acetate significantly decreased the final live body weight, daily body weight gain, while feed intake insignificantly (p<0.01) decreased.Also, giblet percentagewas significantly (p#0.01) affected by lead levels while, carcass or dressing percentages were insignificantly. It can be concluded that, diet formulated in 0.5%garlic can adequately ensure the growth performance in broilers chicks.final live body weight, daily body weight gain, feed conversion ratio and survival rate were significantly (p<0.01) improved while, daily feed intake was significantly (p<0.01) decreased with dietary garlic supplementation. Lead acetate significantly (p< 0.01) impaired live body weight, body weight gain and feed conversion. The interaction between lead levels and garlic supplementation showed that dietary garlic supplementation reversed these deleterious effects of lead intoxication on growth performance traits. Giblets percentage was significantly decreased with dietary supplementation by garlic and lead acetate at different levels, while, carcass and dressing were not affected significantly. These results suggested that garlic supplementation at 0.5% in broiler chicks diets can promotes growth performance traits and reverse the inhibitory effects of lead intoxication on such traits. | ||||
